"Today I look for someone just for me. Someone who will love me even if I can't fulfill their wishes. Someone who has love for me alone."

Chii has an innocent child-like personality and only knows how to do things as she is taught. She seems to care deeply for Hideki, always trying to make him happy, she uses her own money she earns at her job to buy things for Hideki, and even starts to cook for him. Chii tends to copy Hideki in a cute childlike way. Chii sometimes acts erotic around Hideki without even knowing it, causing him to have perverted thoughts.

Otaku Trivia:

1) Like Nyu from Elfen Lied, Chii was named after the first thing she said.

2) Chii was created by CLAMP and was used in 2 two cross-overs.

3) The way Chii is activated (the location of her power button) might actually be a form of sexual joke, to be "turned on".
